The following table represents a hypothetical example of an FTDNA style table for displaying YDNA test results. In this example results for 8 "kits" are shown, organized into two groups, each group presumably sharing a relatively recent common ancestor based on the similarity of their YDNA signatures. This particular example shows only 12 markers; usually a larger number of markers is used in these tests, though many elect to employ only the minimum 12-marker test. In this example, the values of the markers for the kits in each group are identical. This indicates the possibility that those in the same group share a relatively recent common ancestor. Note, however, that 12-marker tests are highly volative; if the kit owners elected to test additional markers, the probability of a common match might change.
*The "markers" shown here are arbitrary, chosen to simplify the display.
In the above table the probability of a relative recent common ancestor is considered to be....
